April wis.] YENDO .■— NOTES ON ALG2E NEW TO JAPAN. VIII. 67 



the distinctions between both species appear to me rather un- 

 reliable. As I have not yet seen any specimen \yhich justifies 

 the amalgamation of these two species into one, I have but to 

 mention our specimen under G. veprecula Kjellm. 



The papillose processes are frequently wanting in a series of 

 the sections of frond. In this case, the specimen is apt to be 

 identified with G. angustifrons. The latter is also founded on a 

 single specimen from Bahia, collected in 184-5. I am rather in- 

 clined to suspect if there might be a papillose part in its frond, 

 the part unfortunately escaping Kjellman's sectioning knife. 

 G. veprecula and G. angustifrons are almost inseparable in the 

 external appearance as well as in the structure of frond, except 

 that the latter has no papillose process on the epidermal cells. 

 In some parts of frond of our specimen I found the epidermal 

 layer entirely lacking of the processes, giving a reason to my 

 doubt. 



Heydrich reported G. canaliculata Kutz. from Formosa in 

 the paper cited above. The specimen kept in the herbarium of 

 the Botanical Museum of Berlin appears to me to be very likely 

 identical with this.

The external appearance of the type specimens of the present 

 species in Dublin shows a very wide range of variation. Some 

 sterile forms may be taken as ChuniJriis puinctattlS Sir., and 

 some narrow-segmented, less branching tetrasporic forms, as C. 



OCellatUS HOLM. It is very likely that tins specie-, has been 



passing under these names among the Japanese botanists. As
